Important Environmental Concerns!

Scientific research has shown that certain man-made chemicals can affect the earth’s naturally occurring stratospheric ozone layer when released to the atmosphere. In particular, several of the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all refrigerants containing these compounds have the same potential impact to the environment. Trane advocates the responsible handling of all refrigerants-including industry replacements for CFCs such as HCFCs and HFCs.

Responsible Refrigerant Practices!

Trane believes that responsible refrigerant practices are important to the environment, our customers, and the air conditioning industry. All technicians who handle refrigerants must be certified. The Federal Clean Air Act (Section 608) sets forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment that is used in these service procedures. In addition, some states or municipalities may have additional requirements that

must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them.

WARNING

R-410A Refrigerant under Higher Pressure than R-22!

The units described in this manual use R-410A refrigerant which operates at higher pressures than R-22 refrigerant. Use ONLY R-410A rated service equipment or components with these units. For specific handling concerns with R-410A, please contact your local Trane representative. Failure to use R-410A rated service equipment or components could result in equipment exploding under R-410A high pressures which could result in death, serious injury, or equipment damage.

WARNI NG

Proper Field Wiring and Grounding Required!

All field wiring MUST be performed by qualified personnel. Improperly installed and grounded field wiring poses FIRE and ELECTROCUTION hazards. To avoid these hazards, you MUST follow requirements for field wiring installation and grounding as described in NEC and your local/state electrical codes. Failure to follow code could result in death or serious injury.

WARNI NG

General Information

Unit Inspection

As soon as the unit arrives at the job site

• Verify that the nameplate data matches the data on the sales order and bill of lading (including electrical data).

• Verify that the power supply complies with the unit nameplate specifications.

• Visually inspect the exterior of the unit, including the roof, for signs of shipping damage.

• Check for material shortages. Refer to the Component Layout and Ship with Location illustration.

Important: If the job site inspection of the unit reveals

damage or material shortages, file a claim

with the carrier immediately. Specify the type and extent of the damage on the ‘bill of lading” before signing.

• Visually inspect the internal components for shipping damage as soon as possible after delivery and before it is stored. Do not walk on the sheet metal base pans.

WARN ING

No Step Surface!

Do not walk on the sheet metal drain pan. Walking on the drain pan could cause the supporting metal to collapse, resulting in the operator/technician to fall. Failure to follow this recommendation could result in death or serious injury.

Bridging between the unit's main supports may consist of multiple 2 by 12 boards or sheet metal grating.

• If concealed damage is discovered, notify the carrier's terminal of damage immediately by phone and by mail. Concealed damage must be reported within 15 days.

• Request an immediate joint inspection of the damage by the carrier and the consignee. Do not remove damaged material from the receiving location. Take photos of the damage, if possible. The owner must provide reasonable evidence that the damage did not occur after delivery.

• Notify the appropriate Trane office before installing or repairing a damaged unit.

When ordering replacement parts or requesting service, be sure to refer to the specific model number, serial number, and DL number (if applicable) stamped on the unit nameplate.

Compressor Nameplate

The nameplate for the “Scroll” compressors is located on the compressor lower housing.

EVP Chiller - Applications Only

If ordered with remote EVP chiller kit, piping components ship in condenser section. The heat exchanger ships separately. The 20-30 chiller nameplate is located on same side as water connections near center left. The 40-120 Ton chiller nameplate is located on same side as water connections near bottom. To view, raise insulation flap over nameplate. Replace and retape insulation flap after viewing.

Phase Monitor (1U3)

The unit is equipped with a phase monitor in the control box. The phase monitor will protect against phase loss, imbalance and reversal of the line voltage. If a fault occurs, the red LED will energize. While the fault condition is present the phase monitor interrupts the 115V control circuit. If no faults are observed, a green LED will be energized.

Manual Motor Protectors (380V through 575V Only):

circuit protection for compressors. These devices are capable of providing both overload and short-circuit protection.

Before operating, the manual motor protector must be switched with the rotary on/off switch to the “ON” position and the overload setpoint dial must be set to the appropriate rating of the motor.

Important: In order to avoid nuisance trips, the

Figure 1. Compressor protection module

Manual motor protectors will be used as branch

overload setpoint dial must be adjusted to the following calculated value:

• Overload Setting = (Compressor RLA) x 1.12

Unit Nameplate

One Mylar unit nameplate is located on the outside upper right corner of the control panel door. It includes the unit model number, serial number, electrical characteristics, weight, refrigerant charge, as well as other pertinent unit data. A small metal nameplate with the Model Number, Serial Number, and Unit Weight is located just above the Mylar nameplate, and a third nameplate is located on the inside of the control panel door.

SS-SVX11H-EN 7

General Information

On 80-120 Ton units, the CSHN*** compressors come equipped with a compressor protection device capable of detecting phase reversal, phase loss, and phase unbalance. The compressor protection device uses a Green and Red LED to indicate the compressor status. A solid Green LED denotes a fault free condition; a blinking Red LED indicates an identifiable fault condition. Once a problem has been detected, the power will have to be cycled to clear the reset circuit.

Note: If the compressor has tripped, the resistance will be

4500 ohms or greater; when reset, they will be less than 2750 ohms.

Blink Code: The blink code consists of different on / off time of the Red LED which is repeated continuously until either the fault is cleared or until power is cycled.

Discharge Line Thermostat

The first compressor on each circuit is equipped with a Discharge Line Thermostat. If the temperature of the line exceeds 230F the thermostat interrupts the 115V control circuit for the compressors and all the compressors on the circuit will de-energize. Once the temperature drops below 180F the thermostat will close and allow the compressor to be energized.

Unit Description

All air cooled condensing units are designed for outdoor installations with vertical air discharge. These units may be installed on a flat roof or placed on a concrete slab at ground level.

Before shipment, each unit is leak-tested, evacuated, a nitrogen holding charge is added, and the controls are tested for proper operation.

The condenser coils an all Aluminum Microchannel design. Corrosion protected condenser coils are a standard option. Louvered condenser grilles for coil protection are standard. Direct-drive, vertical discharge condenser fans are provided with built-in current and overload protection.

For “Ship with” items, see Figure 2, p. 9 and Figure 3, p. 9.

If low ambient operation is required, low ambient dampers are available as a field or factory installed option.

Units may be ordered with one of the following options:

• No System Controls (Field provided controls required)

• Constant Volume Controls

• Supply Air Temperature Control (VAV applications)

• EVP Chiller Controls

Basic unit components include:

• Manifolded Scroll Compressors

• Condenser coils

• Condenser fans (number based on unit size)

• Discharge service valve (one per circuit)

• Liquid line service valve (one per circuit)
